After installation, the insulation is clad with an aluminum
jacket to ASTM B-209 with a laminated 1 mil polyethylene moisture
barrier on the tank side. Standard exterior jacket finish is embossed
"stucco" pattern to minimize glare and resist minor damage. All tank
connections are recessed and the ASME nameplate exposed. All seams
are caulked with aluminum pigmented silicone for weather protection.
